RAMAN-SPECTRA OF CL-3(+) AND BR-3(+) AT 12K PRODUCED FROM THE REACTION OF HCL OR HBR WITH NO2 Academic Article uri icon

abstract

  • The products of the reactions of HCl or HBr with nitrogen dioxide at 12 K have been examined using Raman spectroscopy. For the NO2+HCl reaction spectroscopic evidence for Cl3+, asymN2O2, N2O3, N2O4, ClNO2, ClNO3, NO3, NO2, and symN2O2 was found. For the reaction with HBr only Br3+, was detected due to resonance Raman enhancement effects. These results are consistent with the previously proposed gasphase reaction scheme for HCl+NO2. However, the reaction proceeds further at low temperatures to produce Cl3+ (or Br3+). The Raman frequencies for Cl3+ were observed at 515(3), 462(1), and 236 cm1(2). The Br3+ resonance Raman spectra, which represent the first well documented spectra for this species, show strong fundamental bands at 281(1) and 227 and 238 cm1 (doublet for 2) as well as an overtone doublet at 471 and 487 cm1.
